I'm using the xplatcppsdk and I've started a Playfab Party, and I'd like to backfill the empty spaces in my party. (I don't have a real server)
On my client I've chosen as the host I can call CreateServerMatchmakingTicket, but the request object for this doesn't allow me to set the ServerDetails part of the request that I'd like to use to give the party descriptor to joining players.
Is there a reason this isn't exposed? Can I just hack the header locally to add these fields and it'll work?
